BUY IT!! *by A***E on December 4, 2018* Ok let me start by saying I live in the middle of nowhere Mississippi where the service is really spotty and poor!!! I could get maybe 1bar 4g in the window! It was all we could do to make a phone call... We bought this and my husband installed it within a 20min... We now get 2 to 4 bars with LTE!! I’ve noticed that with my IPHONE 7 I get mostly 2bars with LTE but everyone with an Android phone seems to have full service all with different phone carriers... I ordered the model that supported LTE and was supposed to work better with IPHONE and AT&T... Either way this thing was absolutely worth every penny!! I’m sitting in my living room now using my phone and I NEVER could have done that without this thing!! FIVE STARS!! ### ⭐⭐⭐⭐⭐ Great product *by S***N on December 19, 2018* The product work efficiently and sure is great. My signal use to be so low and slow, but ever since I got this it made my life so much faster. Great product overall and I would string suggest it to people who have bad signals. ### ⭐⭐⭐⭐⭐ Works Great *by S***N on January 19, 2019* The signal booster worked great! It changed minimal coverage to 4 bar LTE coverage. Also the seller is very responsive and helpful with any questions you may have. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/99039439-kkbstr-cell-phone-signal-booster-att-t-mobile-2g-3g](https://www.desertcart.hr/products/99039439-kkbstr-cell-phone-signal-booster-att-t-mobile-2g-3g) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-24*
